Finally, the distribution of the following variables was analyzed in relation to the CKD stages II–V: age (years±SD), gender, duration of in-hospital stay (days±SD), systolic and diastolic blood pressure (mmHg±SD), quantification of serum phosphate, PTH, ferritin, transferrin saturation (all in %), assessment of proteinuria (%), RAAS inhibition (ACE inhibitor/sartan/no inhibition at all—%), and recommendation of oral bicarbonate (%). The gene discussed is TF; the disease is chronic kidney disease.
